Durapipe Replaces Traditional Concrete Drainage System in Palawan

The new Durapipe project in Palawan focuses on drainage improvement intended to enhance water flow in a localized area. An 1800-millimeter diameter Durapipe was delivered and installed to function as a drainage line connecting an estero to the city’s existing main drainage system. The project was implemented to address recurring water buildup in the area, particularly during periods of heavy rainfall.

The drainage connection previously relied on a traditional concrete culvert and reinforced concrete pipes (RCP), which had become less effective over time due to wear, joint leakage, and limited hydraulic efficiency. To improve performance and reliability, the traditional culvert was replaced with Durapipe, a modern pipe system designed to handle large volumes of water while maintaining structural integrity under constant exposure to moisture and soil pressure.

With its smooth internal surface, the 1800 mm Durapipe allows water from the estero to flow more efficiently into the main drainage line, reducing flow restrictions and minimizing the risk of overflow. The large diameter of the pipe ensures that sudden increases in water volume can be accommodated without compromising the system’s function.

Durapipe was selected for this project because of its durability, resistance to corrosion and abrasion, and long service life compared to conventional culvert materials. Its lightweight design also allowed for easier handling and installation on site, helping streamline construction activities. The successful installation of this Durapipe system demonstrates how replacing traditional culverts with modern drainage solutions can significantly improve localized water management and long-term performance.
